This invention relates to calendars, and more particularly to that class'of calendars having relatively movable or adjustable parts, and which are adapted to be used for showingor ascertaining the days or dates of the weeks and months within a given period of time, or for fixing or determining a date or dates.

The principal object of the invention is to provide a simple, economical and eflicient calendar.

A further object of the invention is to provide a calendar which is compact and 'attractive in appearance, durable and convenient to operate, accurate and reliable, and which is adapted to be used for fixing or determining any date within a period of time of any desired extent.

Other and further objects of the invention will appear from the following description and from an inspection of the accompanying drawings which are made a part hereof.

' The invention consists of the features, com- 'binations, details of construction and arrangement of parts herein described and claimed.

Fig. 8 is a developed view of the cylindrical month-indicating member which surrounds the week day name indicating chart or member and contains the abbreviations of the names of the months and corresponding openings one for each month, for uncovering and disclosing the corresponding week day name on the encircled week day name indicating chart or member; and I Fig. 9 is a front View of the slide or table containing the numbers for indicating the 6 days of the month by number.

In constructing an improved calendar in accordance with this invention, I provide a frame or casing 1 having a front wall or panel 2 which may be formed of sheet metal and is provided with a plurality of windows or window-like apertures 2, 3 and 4 for disclosing numbers visible through the opening 2, for indicating the year or years respectively corresponding with a given date or period of time; the names or abbreviations of the names of the months, and the week day names or abbreviations of the names of the first days of the months respectively as made visible through the opening 8 which may be in the form of a single opening or of two separate openings in alignment; and the numbers contained on a slide or table 5 and made visible through said opening 4, for indicating the days of the months by number.

The front wall or panel 2 of the casing is, by preference formed of an inner backing plate 6 of stamped sheet metal which is bent along all of its margins to form a continuous marginal flange 7 which extends entirely around the margin of the sheet and forms a rigid marginal reenforcement along all of the edges of the sheet and at the corners of the panel, the said metallic sheet being covered by a front cover sheet 8 of celluloid or similar material having its edges folded over the edges and back of the marginal flange or flanges 7, and clamped between said flanged marginal portions and the flanged margins of a metallic back wall member 9 having angular marginal flanges 10 which are overlapped and surrounded by the marginal flanges 7 and adapted to engage and hold the folded edges 11 of the flexible covering sheet 8 between said marginal flanges 10 and 7. The panel 2 thus formed, is hollow, and forms a casing having a closed chamber or compartment 12 between the spaced-apart front and back walls of the panel in which the'slide or table 5 containing the numbers for indicating the days of the months by number is slidably mounted in and between grooved tracks 13 which are by preference in the form of marginal angular flanges formed by bending the corresponding margins of the opening 4: in

the metal backing sheet 6 inward and into position to overlap and slidably engage and support the slide 5 in operative position on the inside of the panel or casin The windows 2, 3 and a consist, ence, of openings in the metallic inner sheet 6 covered by transparent material.

A handle 14 fixed to the slide .6 extends through an opening in the back wall 9 of the panel or casingand serves as a convenient means for enabling the operator to slide the said slide 6 between the parallel tracks 13 into position to exposethe desired numbers printed on said slide or table in position to be visible through the opening 4; and in the proper position relatively to the abbreviations 15 of the names of the week days which are printed along the upper margin of the opening at, so that the weekday names of the days of the month made visible through the opening l will beshown, and the days of any given month will be designated and exhibited in .their proper oruer and may bereadily identified and distinguished by their week day names and numbers respectively.

' .Thefront cover sheet 8 is, by preference, opaque except that those parts of the cover which cover the openings 2, 3 and i, respectively, are transparent. And the cover sheet may be of any suitable material, such, for example,-as celluloid or glass, in whole or in part.

A back casing member or wall 15, which is,'by preference, formed of sheet metal and parti-cylindrical, is secured to the back cas ing wall member 9 by means of integral marginal lugs 16 on the straight margins of said member 15 which are inserted through openings in the casing wall member 9 and bent so as to form a rigid connection between the parts thus secured together. Aparti-cylindrical compartment 17 is thus formed back of the compartment 12 in the front hollow panel,

said rear compartment 17 being closed at its oppositeends by end walls 18. Legs 19 are provided which may be attached to or formed integrally with the said end walls 18, respectively; and the back wall member 9 has an opening 20 therein which may extend from end to end of the compartment 17, or thereby preferabout, and 'afiords communication between said compartments.

- Rotatively mounted, by preference, within the casing and upon a fixed non-rotative axle 21 which extends through the compartment 17 and has its opposite ends rigidly secured to and supported by the rearwardly projecting frame members orwalls 18, or other stationary supports, is a cylindrical device or cylinder 22 which, by preference, comprises a plurality of concentric annular or telescoping clindrical members, including an nner cylinder 23, which is a week day name indicator or week day designating member, and an outer cylinder 2%, which is a month indicator or month designating member. The perforated cylindrical wall of the outer cylinder 24 encircles and covers the cyl ndrical peripheral wall of the said inner cylinder; and the inner and outer cylinders 23 and 24; arerotative relatively to each other, and are adapted to rotate in either direction either together or independently of each other around said stationary axle. The inner cyllnder 23 has an end wall 25 the outer peripheral margin of which is folded over a peripheral endfiange 26 at the closed end of said cylin der, thus forming a projecting peripheral annular flange 27 whichprojects through an opening 28 in the front wall of the panel. The outer cylinder 2% has a similar end wall 29"the outer peripheral margin of which is folded over a peripheral end flange 30 at the closed end of said cylinder, thus forming a knurled peripherally projecting annular flange 31 which projects through an opening 32 inthe front wall of the panel. The margins of the openings28 and 32 are covered by flanged metallic eyelets or thimbles 33.

A third concentric annular member or cylinder 34, which is'a year or indicator, encircles the inner cylinder 23, and is adapted to rotate with and movable endwise longitudinally of said inner cylinder.

This relatively short loosely mounted longitudinally movable annularsleeve or cyl nder 34 isoperatively connected with a stationary non-rotative feed screw 35 fixed to the stationaryaxle 21, by means of an inwardly projecting radial arm 36 which is fixed to said annular sleeve or cylinder 34 and extends inward from the latter through a longitudinal peripheral slot 37 in the cylindrical wall of the inner cylinder 23, said radial arm being provided at its inner end with a lielically threaded opening or bore 38 formed on the inner side of a loop 33 which encircles the screw 35. The inner helical threads e0 in the bore 38 formed by said loop on the arm 36 are in screw-threaded engagement withthe outer helicalscrew threads 4210f the stationary non-rotative feed-screw 35 which extends longitudinally of the axle or shaft 21 a suf ficient distance to cause the annular sleeve or cylinder 34 to move endwise longitudinaldesignating member cylindrical wallportion of the inner cylinder 23 and is movable longitudinally of said inner cylinder between the adjacent inner end of the outer cylinder 24 and the outer or closed end of said inner cylinder 23, and that said year designatingmember or sleeve is located inside ofthe front wall portion of the panel or casing in which the window or opening 2 is located, so that said sleeve, or some part of the periphery of said sleeve is always ex posed and visible through said window opening.

The year designating member or sleeve 34 turns with the inner cylinder 23, or week day designating member, whenever the latter is rotated in either direction around the non rot-ative feed screw 35 which is operatively connected with said sleeve 34, and causes said sleeve to moveendwise during such rotative movements. It follows, of course, that the peripheral movement of said sleeve is in a helical path past the stationary window-like opening'2 in the front casing wall, and corresponds with the direction and pitch of the helical threads ofsaid feed screw.

The year designating member or sleeve 34 is provided with a, multiplicity of year-designating numbers 42 representing or designating the years in the consecutive order in which they occur for a given period of time in this instance, ninety n'ine years from 1901 to 1999, inclusive, although any desired num ber of years may be designatedarranged in a helical column or row 43 around the periphery of said year designating member or sleeve along and in conformity with the direction and pitch of the helical path of movement of the periphery of said sleeve. Said helical column or row 43 of year designating numbers extends, 'bypreference, more than once around said sleeve, forming a plurality of complete circumferential laps or windings,'in this instance three complete laps and part of a fourth, each circumferential lap or winding containing, by preference, twentyeight year designations, each year being designated on said sleeve 34 by the last two numbers of the complete date number of theyear, for example 28 for the year 1928, the century number 19 being, by preference, on the front face of the panel or casing adja cent to the left margin of the window opening 24 at the point indicated by the reference numeral 44. (See Figs. 1, 3 and 6.)

The year-designating numbers included in the helical column 43 in the same consecutive order in which the designated years occur, are also arranged in horizontal columns 45 which extend longitudinally of the sleeve and are, by preference, twenty-eight in number, one horizontal column for each year-designation in the respective circumferential laps or windings of the helical column. Each of said horizontal columns or rows 45 contains individual yeardesignations for each of a plurality of years all of which have the same week days constituting the first days of corresponding months of any and all of said designated years: For example, in the years 1901, 1929, 1957, and 1985, the year-designations of which are all shown in one horizontal column at the top of Fig. 6, the first day of January of each of said years is Tuesday; each Feb. 1 is Friday; each March 1 is Friday; each April 1 is Monday; each May 1 is Wednesday; each June 1 is Saturday; each July 1 is Monday; each Aug. 1 is Thursday; each Sept. 1 is Sunday; each Oct. 1 is Tuesday; each N ov. 1 is Friday; and each Decemi ber 1 is Sunday; and so on throughout the entire series of, preferably twenty-eight horizontal columns 45. (See Fig. 6, and Fig. 3.)

By reference to Fig. 7 it will be seen that the inner cylinder 23, which is the week-day name indicator or designating member, is provided with a multiplicity of week-day name abbreviations or designations printed or otherwise placed on the periphery thereof and arranged in circumferential columns 46 around said periphery and corresponding with the twelve months of the years, and in horizontal columns 47 which correspond with the years.

The horizontal columns 47, of which there are, by preference twenty-eight, each in alignment with a corresponding horizontal column 45 on the endWise-movable year-designating sleeve member 84, are equally spaced apart circuinferentially of the inner cylinder 23, like the corresponding horizontal columns 45 on said year-designating sleeve member. For the sake of brevity the twelve circumferential columns 46 on the inner cylinder 23 may be designated as month columns. Said columns 46 are twelve in number, and are, by preference, arranged in parallel relation in consecutive order corresponding with the order in which the months occur; and each of said circumferential columns or month columns contains the abbreviations of the week day names or designations of the first days of a corresponding month for a series of years, each of said week-day names or designations being in alignment with a corresponding horizontal column 45 of year designations on the endwise movable year-designating sleeve member 34. (See Figs. 6 and 7.) I

For example, the first circumferential colall) umn or month column 46 011 the periphery of. the inner cylinder 23 corresponds with and represents the month of January in any and al of a series of years, said years being designated on the endwise-movable yeardesignating member or sleeve 34; and said column contains the abbreviations or week day names or designations of the-first day of January in any and all of said series of ears. The second column 46 corresponds with the month of February, and contains the week-day designations of the first day of February for any and all of said years. The third month column 46 corresponds with March throughout the entire series of years, and so on throughout the entire series of twelve columns 46 and the corresponding months from January to December, inclusive, corresponding with said columns respectively. It should be noted that there are only twenty-eight designations in each column 46, and a like number of horizontal columns 47 on the inner cylinder 23, and a like number of columns on the endwise-movable year-designating sleeve 34 for the entire series of ninety-nine years.

The outer cylinder 24, which is the monthdesignating member, comprises a perforated cylindrical wall portion 48 which encircles and covers the portion of the inner cylinder 23 on which the table of week day names or designations is contained.

Said cylinder 24 is provided with the names or abbreviations of the names designating the twelve months printed or otherwise placed on and arranged in consecutive order circumferentially around the said cylinder,

7 by preference, at or near the outer closed end thereof. The month names or designations 49, including the twelve months'from J an uaryto December inclusive, in their consecutive order, are uniformly spaced apart circumferentially around said cylinder; and the cylindrical wall portion 48 which encircles and covers the week-day names or designations on the inner cylinder 23, is provided with twelve windows or window-like openings uniformly spaced apart arranged in a helical row around said cylindrical wall portion 48, each of said openings 50 being in horizontal alignment with a corresponding month name. or designation 49.

Each of the perforations or window-like openings 50 corresponds with a month, the name or designation 49 of which is located in horizontal alignment with such opening. And said window-like openings are, by preference, arranged in consecutive orderlongitudinally of the cylinder in the order in which the months occur, as well as circumferentially; and each is located over and adapted to uncoverthe week-day name abbreviations or designations contained in a, corresponding 7 month column 46 on the periphery of the inner cylinder 23, successively, whenever a givposition at the window opening 2?, the proper horizontal column 47 on inner cylinder 23 containing the designations of the week day names of the first days of the twelve calendar months of such selected year being brought to position to be uncovered andjexposed in reading position at window-opening-3 in alignment with said exposed year designating number by the same operation. The month designating cylinder 24 is then rotated to position to bring the month name or designation of any selected months into exposed reading position at the window-opening 3, or

in alignment with the exposed year-designau ing number; and, bythe same operation of said month-designating cylinder, a corresponding peripheral opening or' perforated wall portion 50 of said cylinder 24' is brought to position to uncover and disclose the week day name or designation of the first day of such selected month in exposed reading position in alignment or concurrently with such disclosed month name or designation, and in alignment with said'exposed-year designating number. The table or slide 5 containing the numbers designating the days of the month by number in their order, is then moved by the operator into position to bring the number 1 designating the first day of such month adjacent to or opposite the stationary week day name designation 15, at the margin of window opening 4, which corresponds with the week day name designation of the first day of said month so exposed on the week day name designating cylinder.

The year designating number of any selected year,lthe month name or designation of any given or selected month or such year, and the week day name of the first day of such selected month are thus, all uncovered and exposed in reading position, and, by preference, in alignment, concurrently. he exposed week day name designation signifies that the slide 5 or table of numbers designating the days of the month by number in their order, is to be moved into position to bring the number 1 designating the first day of the selected month into positionadj acent to or opposite the corresponding stationary week day name or designation at the margin of said slide or table, thereby uncovering and exposing the numbers of all of the days of such selected month in their proper relation to each other and to the marginal week day name designations at the window opening 4, as already described.

The helically threaded feeding means including the stationary feed screw 35 and the engaged screw-threaded radial arm 86 on the year designating cylinder or sleeve 34: serves as a means for imparting endwise movement to said year designating member concurrently with the rotation of the latter and of the inner week day name designating cylinder 23. This movement of the week day name designating cylinder endwise relatively to'the week day name designating cylinder and the-movement of the year designating numbers in a helical path of movement cor-.

respondingwith the helical columns of said 7 numbers on the year designating cylinder,

, posed month designations, and a rotative causes said year designating numbers to be uncovered and exposed in reading position successively concurrently with respect to the corresponding exposed week day name designations and months designations. -The year designating cylinder 34 is obviously capable of being operated manually to obtain the desired endwise movement but- I prefer to employ the helically threaded feeding means for that purpose. The circumferential columns of year designations should be helical and should correspond with the helical'windings of the feed screw when the above described feeding means is employed; but the circumferential columns may be either helical or in the form of complete annular parallel circumferential columns in case the mechanical means for imparting endwise movement to said cylinder is dispensed with.
